This webpage aims to give access to practical tools on environmental risk assessment and management of chemicals. It describes the work flow of environmental risk assessment and management with links to relevant OECD products that can be used in each step of the work flow. The Toolkit has been revised 1) to include resources other than OECD products, and 2) to incorporate three examples (i.e. textile dye, pesticide and environmental quality standard setting) which show the risk assessment steps involved in each case.
